Zak, I feel so lucky to have had you as a friend. You were kind, loyal, and had so much curiousity and intelligence. From when we first met at Manchester Uni you've been such a good friend to me. I will always remember meeting up in Bristol and catching up, listening to you talk enthusiastically about your robotics work and hearing your pride in it. I can't believe you're gone. You'll be missed Carla xx
